Tonsilitis

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. 

Symptoms:

Tonsillitis most commonly affects children between preschool ages and the mid-teenage years. Common signs and symptoms of tonsillitis include:

  • Red, swollen tonsils
  • White or yellow coating or patches on the tonsils
  • Sore throat
  • Difficult or painful swallowing
  • Fever
  • Enlarged, tender glands (lymph nodes) in the neck
  • A scratchy, muffled or throaty voice
  • Bad breath
  • Stomachache, particularly in younger children
  • Stiff neck
  • Headache
  • In young children who are unable to describe how they feel, signs of tonsillitis may include:
  • Drooling due to difficult or painful swallowing
  • Refusal to eat
  • Unusual fussiness

Causes:

Tonsils are your first line of defense against illness. They produce white blood cells to help your body fight infection. The tonsils combat bacteria and viruses that enter your body through your mouth. However, tonsils are also weak to infection from these invaders. Tonsillitis can be caused by a virus, such as the common cold, or by a bacterial infection, such as strep throat. 

Viruses are the most common cause of tonsillitis. The Epstein-Barr virus can cause tonsillitis, which can also cause mononucleosis.

Children come into close contact with others at school and play, exposing them to a variety of viruses and bacteria. This makes them particularly weak to the germs that cause tonsillitis.
